black spots on screen right when the phone is almost shut down... - Galaxy S II General

I just noticed it today, when i woke up... Turned my phone on and off... And just when the samsung logo is gone, and the screen is not completely black and the back and menu button are still on. I could then see black dots on the screen, i tought it was something on top of it, but couldn't wipe it off...
I put it onder a light and saw nothing... very strange... What could this be??
I tried it again and again, and it was always the same...
Can someone try this in a dark room? to see if you have it too.
Could it be influencing my screen? I don't think i see it when my screen is turned on.
Thnx

I have seen those on 2 SGS2's.

Ah ok...Nothing to worry abouth than? you saw one without it too? It's only the 5 seconds when the phone is in this not complete black when the back and menu button are still on before shutting down completely.
But I don't know if this influences my screen or if it's just normal. What could it be?

Hey i've got an sgs2 with this similar problem of black spots on random part of the screen when i shut down my phone. it can be seen before the phone vibrates off. Is urs fixedd?? or sent for replacment??

screen stays black after standby

have android desire build on my hd2 and it works great...if i put my phone in standby for a few seconds it comes back on just fine but if its in standby for a few minutes only the keys light up and i have to pull the battery..i was reading some posts and thought i saw something about deleting the data.img....was wondering if this was the solution to the problem or something else..
If you have a black screen and the button lights are on, you can stick it under a bright light and turn it on. It should come on after that. If that's the case then turn off automatic brightness and see if that corrects the issue.
auto brightness wasnt on when i went to go change it...i flipped to it just to see if it would do it but it does the same thing..if in standby for too long,the buttons light up and the screen lights up black but thats it.

Strange black screen problem in Defy

Hi!
I dropped my defy in 2 cm of water,everything was fine for 20 min, suddently my screen stop responding, i removed the battery, place it back turn on the sceen got quite dark. Yet I was still able to see things on screen. Then it slowly got darker and darker until it was completely black. After that I tried to push the power button but the screen didn't light up, only the 4 buttons were lit.
I noticed I was still able to unlock the screen or answer phonecalls sliding my finger from left to right on the correct area of the screen, although it remainded black all the time.
What can i do? do i have to replace the lcd?
Thanks

[Q] Auto-dimming bug

Great phone but, it appears to be a bug with the screen dimming.
Regarding settings, I have everything turned off. Adapt display is off. Auto-brightness is off. Auto-adjust screen tone is off also.
I know Samsung displays dim if the phone overheats but my phone will auto-dim even if the phone is cool.
What I've found out is that the phone will only dim "permanently" when the screen is about to shut off.
For example: Set the screen shut off to 30 seconds and around the 28 second mark, the screen will dim for a couple of seconds before it shuts off. This is where the auto-dimming will "permanently" kick in. When the screen dims at the 28 second mark for a second, i'll touch the screen so it doesn't shut off. But by this time, the screen has dimmed already and won't go back to the regular brightness. I have to lock and unlock the phone for the dimmed screen to go away.
This scenario has happened every single time. Extremely annoying.
Anyone else experience this?

Yes, same here. It happens alot. Not every single time, but alot of the times.
Try this...
Hi
As the other user said it might be the software bug.
Please try this app. Disable your auto brightness and install this software https://play.google.com/store/apps/details?id=com.vitocassisi.luxlite
This lite version is free. Try this. If everything works, you may consider the paid version to support the dev guy...

Is the phone rooted ?
If not try connecting to a pc and run kies to see if it reboots that way.
If it is rooted try to reflash thru odin.

How long have you had the phone under 2 years still under warranty.
i didnt buy the phone nor do i know who did so i wouldnt know and in addition the screen is cracked so i dont know if they would even cover that by any chance do you know where i may get a cheap lcd digitizer ?

That was my point..
It must be broken or the digitizer connections must be loose..
You said it..its broken
Check ebay or somewhere..you'll find plenty..

Black screen after dropping the phone

So yeah I dropped my phone on its side, while the screen didn't crack at all and nothing happened at the time of the drop, after I woke up the next day my phone had this yellowish small circle on the left then this circle started growing to cover most of the screen and then it started to go brown then black and now the whole screen is black, the touch and the led lights are working, I know I should take it to a specialist or something but for the time being is there anything I can do or check to make it work again by myself ? thanks.
Nothing you can do .
